Üdvözlet mindenkinek.Javításra hozták ezt a készüléket,de az előző szakember kiszedett belőle két alkatrészt és elfelejtette visszatenni.Ha van valakinek rajza hozzá megköszönném.A panelen csak ennyi van:Velocity VD1002 REV:A2.Egyébként a Q203 és a Q204 hiányzik.Ez érdekelne hogy mi volt.Előre is köszönöm.
Sziasztok,
Javitom a cimben szereplő kazettás magnetofont. Hibajelenség: bekapcsolás után mérve a szalagsebesség névleges értéken van. Az idő múlásával melegedik a motor és az inditó kondenzátor is, moközben a sebesség a hőmérséklet növekedésével csökken. Valószinüleg a kondenzátor lesz hibás. A kondenzátor mérete:d=20mm X 35mm Mivel tudom helyettesiteni a hibásnak vélt kondenzátort?-Ajánlott kondenzátorral jó-
Köszönöm
Sziasztok!
Múlthéten kaptam 2db ORION hangfalat.
A hangszórójáról találtam leírást, de hogy mi lehet a konkrét típusa a ládának arról nem.

Vagy esetleg tartozott-e valamilyen rádióerősítőhöz...egyéb?
Előre is köszönöm a fáradozásokat!
I have a Victor QL-Y77F turntable that one day started to miss the speed lock. Even when the motor is in stop mode, the platter still rotates a little bit (random actually) backwards. When is in START mode (33 or45rpms) the speed randomly jumps from green to red and back, meaning from stable to unstable.
I tried to replace the Crystal and then the Hall generators but with no luck. Actually without the service manual is pretty difficult. Do you have any ideas what to do further?
TIA
Corneliu
